Siemens 5SL7106-3RC Miniature Circuit Breaker 6A 1-pole K 15

The Siemens 5SL7106-3RC is a 1-pole miniature circuit breaker rated 6 A with a K characteristic and 15 kA breaking capacity. The K characteristic means it trips between 8 and 12 times rated current — designed for motor and inductive loads where a brief inrush must not cause nuisance tripping, while still providing short-circuit protection. The 15 kA breaking capacity at 230/400 V is the maximum fault current it can safely interrupt without welding contacts or failing to clear; in a panel with a high available fault current, this rating determines whether the MCB coordinates with the upstream breaker or requires a current-limiting device ahead of it.
